Tunnel Structures

CALL EXPERT

 

Rail & transit:

In urban centers and airports, the underground builds of transit systems must be planned to minimize surface disruption throughout the construction process. We provide the geotechnical, structural, and tunneling skills you need, and complement them with track design, signaling, communications, traction power, ventilation and emergency egress, rail activation, and systems commissioning.

Roadway tunnels:
As highway infrastructure expands around the world, the need for large-diameter and large-bore tunnels grows. With our comprehensive civil, structural, and transportation engineering expertise, we bring critical knowledge and experience to the early stages of these visible, long-term projects.

Pedestrian tunnels:
Underground occupied spaces require a truly integrated, multidisciplinary approach to provide a safe, accessible, and pleasant user experience. Our design services are complemented by our expertise in the architectural, mechanical, electrical, and fire-life safety disciplines, allowing us to provide a fully-integrated service.

Water tunnels:
Globally, water supply and distribution systems must remain operational for extended periods of time. Yet they need constant repair, upgrading, and expansion. We’re experienced in investigation of existing tunnel system and provide the detailed report of replacement process of water conveyance systems, from small-diameter pipelines using horizontal direction drilling, to some of the largest and longest machine-bored tunnels.
